How can you remove porosity from the gold product

Question

Accepted Answer

Porosity in gold products can be removed through various methods.

One method is to use a vacuum or pressure casting technique to eliminate air bubbles and achieve a denser structure.
Another approach is to use a process called burnout, where the gold is heated to a high temperature to vaporize any trapped gases.
Using a flux during the casting process can also help reduce porosity by preventing oxidation and promoting better metal flow.
Properly controlling the cooling rate during solidification can minimize porosity as well.
Post-casting treatments like heat treatment or hot isostatic pressing (HIP) can be employed to further improve the density and reduce porosity.

Accepted Answer

There are 2 ways to remove porosity 
1 we need to hammer where the porosity is visable and apply ambry paper.
2 If there is more deep porosity need to hammer and then lazer the product this is how porosity will go from the product.
